The chest 1 is constructed by a wooden chest body 11 and drawings 12 made of a synthetic resin. The above described chest body 11 is formed into a rectangular shape by a bottom plate 14 provided with leg parts 13, side plates 15 and 15 vertically provided at both side portions of the bottom plate 14, a back plate 16 vertically provided at a back side of the above described bottom plate 14, a top plate 17 provided at an upper end of the above described side plates 15 and 15, and the above described back plate 16, as shown in FIG. 1 and FIG. 2. Three of the above described drawers 12 are housed in a front opening of the chest body 11 to be able to be drawn, and are constructed to be able to house and store material goods in the drawers 12.

The above described drawer 12 is constructed by a drawer body 21 in a rectangular container shape, and a front plate 22 mounted in the state in which it is locked at claw parts 21 a and 21 a (see FIG. 4) of the drawer body 21, and the above described drawer body 21 and the above described front plate 22 are formed to be semitransparent and constructed to be able to confirm an inside.

The front plate 22 is formed to be light blue and transparent, and the above described drawer body 21 is formed to be white and transparent. Note that the above described front plate 22 and the drawer body 21 may be formed to be not only semitransparent but also formed to be transparent, or opaque, and in the case of opaque, they can be also colored. At this time, the above described front plate 22 and the above described drawer body 21 are constructed by separate pieces, and therefore, the above described front plate 22 and the above described drawer body 21 can be set to be the same color, or can be set to be different colors. As a result, the appearance quality can be enhanced and variation can be increased.

A recessed part 23 is provided at a lower portion of the above described front plate 22, and a step part 24 on which a hand can be laid at the time of drawing is formed between the recessed part 23 and the ordinary part. The step part 24 is formed into a bow shape with a central portion projecting upward, and the operating force applied to the step part 24 is applied to a later-described rail 25 which supports the drawer 12 at the chest body 11.

Metal rails 25, which are supported at a rail not shown provided at an inner surface of each of the side plates 15 and 15 of the above described chest body 11 and slidably support the drawer 12 at the above described chest body 11, are fixed to both side portions of the above described drawer body 21, and the drawer body 21 opened upward has its upper end portion reinforced by the rails 25.

The rail 25 is formed by folding a long metal plate, and a flange 31 extending toward the above described drawer 12 is provided at the lower edge portion, as shown in FIG. 3. Screw insertion holes 32 and 32 are provided at both end portions of the flange 31 and a raised wall 33 rises from the side edge of the flange 31. A guide surface 34 extending in the direction to separate from the above described drawer 12 is provided at an upper edge of the raised wall 33, and a bent part 35 which is bent downward is formed at a side edge of the guide surface 34. The above described guide surface 34 is notched at one end portion of the rail 25, and a roller 37 a part of which projects from the above described guide surface 34 is rotatably supported at a region of the above described raised wall 33 in a notched part 36.
